ABSTRACT:
An electronic still camera using a memory card as a picture recording medium, and a memory card applicable thereto and implemented by an EEPROM (Electrically Erasable Programmable Read Only Memory). A picture signal generated by a CCD array and representative of a picture is routed through an amplifier and an analog-to-digital converter to a signal processing circuit. The picture signal is subjected to interpolation and other similar processing by the signal processing circuit, coded by a compressing circuit, and then written to a buffer memory. These steps proceed on a real time basis. The buffer memory is constituted by a storage device having a reading speed and a writing speed which are different from each other. A memory card controller reads data out of the buffer memory and writes them in the memory card at a low speed matching the memory card.
